IS 11169 (Part 2) X12Cr13 vs BS 970 (Part 3) 420S29

Strong Match — 88.4% match based on chemical composition and mechanical property overlap.

IS 11169 (Part 2) X12Cr13 (IS 11169 (Part 2):2023) and BS 970 (Part 3) 420S29 (BS 970 (Part 3):1991) are both steel grades. Both fall under the Stainless Steel category. IS 11169 (Part 2) X12Cr13 is typically used for cold heading and cold extrusion of stainless steel parts; the standard covers wires, wire rods and bars of 0.8 to 100 mm (clause 1.1, table 14), while BS 970 (Part 3) 420S29 is commonly used for bright cold finished bars (cold drawn, turned or precision ground) for general engineering purposes, in straight lengths; martensitic stainless steel (table 17). IS 11169 (Part 2) X12Cr13 is defined under Bureau of Indian Standards (IS), originating from India, while BS 970 (Part 3) 420S29 is defined under British Standards (BS), originating from United Kingdom.

As per chemical composition, IS 11169 (Part 2) X12Cr13 vs BS 970 (Part 3) 420S29 is a 88.4% match. Mechanical property data is not available for both grades, so this factor could not be scored. Combined, this makes them a strong match overall at 88.4%.
